Desmos Unlocked

IMPORTANT: As of December 2022, Desmos appears to have ended support for defining custom symbols through the MathQuill API that this extension relies on. As a result, the core functionality of this extension no longer works. Please see issue #14.

Write beautiful equations in the Desmos graphing calculator by customizing the underlying math formula editor from an easy-to-use control panel.

Desmos provides shortcuts for a limited amount of symbols (e.g pi, theta, sqrt) by default and this browser extension expands shortcut functionality to the rest of the Greek letters as well as to some common and more advanced mathematical symbols.

Support for the following features planned:

• Custom, user-defined shortcuts for supported symbols
• Recognition of arbitrary Unicode characters in the calculator
• Customization of recognized function names

Building from source

Operating system requirements

All instructions have been tested on macOS Monterrey 12.0.1 and Ubuntu 22.04, but any modern OS should work.

Necessary tools

npm is necessary. Instructions have been tested with npm version 8.10.0 and node version 18.0.0. These tools can be downloaded from https://nodejs.org/en/download/.

Commands to run

In the project root directory (where package.json is located), first run:

npm install

Once npm has finished installing dependencies, run:

npm run app:firefox, npm run app:chrome, npm run app:edge, or npm run app:opera
